摘　　要：分析了位置服务信息终端的特点,针对其不足,采用了网络与自主导航相结合的设计方案,提出了预先存储地图数据和实时下载增量更新的思想,并在此基础上设计了基于网络与自主导航相结合的LBS移动信息终端,旨在为LBS应用层的研究提供硬件支撑。介绍了终端的主要功能,重点描述了终端的软硬件设计,基于该终端,实现了一个原型系统。The characteristics of LBS information terminal is analyzed, and in allusion to its disadvantages, a solution concerning the design ofmobile information terminal is proposed. It is based on the combination ofnetwork and independent navigation, and the thought of storing map data in advance and downloading increment in real time, with the purpose of providing a hardware supporting platform for the research of LBS on the application tier. The main functions of the terminal are introduced and much emphasis is given on the software and hardware design of the terminal. A prototype system is achieved based on the terminal.
